Question: Are you able to please describe how dye sublimation printing works? What type of printer is commonly used? Will it be exactly like heat transfer printing?
Answer: Wow! All great and related inquiries to the dye sub and heat transfer printing of fabric, one of the best methods to print fabric along with other items, although this answer will deal mostly with polyester fabric.
First, there are 2 varieties of transfer paper. One uses ribbon so transfer color to your transfer paper, as well as the other is identical basic printing method as digital printing except there are differences between ink and dye. As well as the same printers works extremely well, while not interchangeably due to differences between dyes and ink.
Inkjet printing uses, typically, what is known as the “four color process” printing method. The four colors can also be known in shorthand as CMYK ink colors. CMYK is short for Cyan-Magenta, Yellow, and Black, which in any combination will print just about any color, excluding neon colors or metallic colors, but many colors from the photo spectrum.
Because of the limitations of CMYK inks, additional colors have been included in some printers that are now called 6 color digital printers, having added a mild cyan as well as a light magenta to attain a few of the harder colors to create within the printing process. Some printers have even added orange and green cartridges too.
Dye sublimation printing is slightly different. The dyes used are exactly like ink, although with some differences. The ink looking for dye sub printing can be another four color process (commonly known in shorthand as 4CP), but the shorthand version here is CMYO, or cyan-magenta-yellow-overprint clear. Where is definitely the black, you might wonder? It would be hard to generate a full color spectrum without black!
To clarify in which the black went, or rather more accurately, where it comes down from in CMYO dye sublimation printing, I have to delve into the rest of the way it works. As stated previously, a typical 4CP computer printer is required to print dyes as well, although the dye should be printed with a treated paper cleverly named “transfer paper.”
An image is printed in reverse (or mirror printed) around the neon sublimation ink. The paper is matched as much as a part of fabric. The fabric cannot be an organic fiber due to process that can be explained momentarily. The material typically used most of the time is polyester because it is a versatile fiber that can be intended to appear like everything from an oil canvas to a sheer fabric into a double-sided knit material which can be made right into a double-sided flag or banner.
Once the paper is matched to the fabric, it really is run through heated rollers at high-pressure. The rollers are heated to simply under 400 degrees Fahrenheit or 210 degrees Celsius. As the fabric passes through the heated rollers, a couple of things happen. First, the pores or cells from the poly-fabric unlock, while simultaneously the dye in the paper is changed into a gaseous state. The gas impregnates the open cells which close as they leave the heated rollers. This produces a continuous tone print which can not be achieved utilizing an inkjet printer due to dot pattern laid down by the inkjets.
If the item for example plastic or aluminum is coated with a special polymeric coating, these materials can also be printed. Besides banners and posters and flags, other items that happen to be commonly dexupky33 with dye sublimation heat transfer printing are clothing items including T-shirts, table covers, sportswear, ID cards, and signs.
Some benefits of heat transfer film is the fact that image is a part of the fabric, so that it doesn’t remove like ink on the surface of fabric or other materials and can not fade for quite some time. The dye cannot build up on fabric like t-shirts either. Everyone had worn a printed shirt where the ink felt like it was very stiff on top of your material, as well as over time it will flake off. This will likely not happen with dye sublimation.
Other advantages are that the colors can be more brilliant than other printing due to the technique of dye sublimation and also the continuous tones which can be achieved if the dye converts into a gaseous state. Because in printing garments the material is printed ahead of the shirt or jacket is constructed, the picture can go to the edge of the material which happens to be not achievable typically with screen printed shirts.
